Question

firmeware bin size is smaller than 3M and upgrade failure

Closed this issue 8 years ago · 1 comments

We have built the firmware for several times following the steps in the project and works out the bin file, however the 7688 DUO board WIFI LED keeps light after upgrading with the firmware bin file, which means the linux kernal initialization failured.

We have compared the compiled bin file with the one download from the office site, the file size is 3M VS 21M. What's wrong about the bin?

I have found the issue is lack of wifi binary for 3.18.45, and cp mt_wifi.ko.3.18.44 to mt_wifi.ko.3.18.45 to make through.
